Method and electronic device for dispersing noise signal

Abstract

An electronic device comprises: a first signal line configured to transmit a noise signal; a filter configured to transmit at least part of the noise signal from the first signal line; and a second signal line configured to transmit the at least part of the noise signal transmitted via the filter, wherein both ends of the filter are connected to the first signal line and the second signal line.

1 ] An electronic device comprising:
 a first signal line configured to transmit a noise signal;   a filter configured to transmit at least part of the noise signal from the first signal line; and   a second signal line configured to transmit the at least part of the noise signal transmitted via the filter,   wherein both ends of the filter are connected to the first signal line and the second signal line.   
     
     
         2 ] The electronic device according to  claim 1 , wherein the filter comprises at least one of a diode, a varistor, and a suppressor. 
     
     
         3 ] The electronic device according to  claim 1 , wherein the noise signal corresponds to an electro static discharge (ESD) signal or an electrical overstress (EOS) signal. 
     
     
         4 ] The electronic device according to  claim 1 , wherein the noise signal flows from an outside into an inside of the electronic device through an input/output connector. 
     
     
         5 ] The electronic device according to  claim 1 , wherein the first signal line and the second signal are in a parallel. 
     
     
         6 ] The electronic device according to  claim 5 , wherein the first signal line and the second signal line connect an input connector and a processor. 
     
     
         7 ] The electronic device according to  claim 5 , wherein the first signal line connects an input/output connector and a processor, and the second signal line connects another input/output connector and the processor. 
     
     
         8 ] The electronic device according to  claim 1 , wherein the filter is short-circuited when transmitting the noise signal in an open state. 
     
     
         9 ] The electronic device according to  claim 1 , wherein the first signal line and/or the second signal line comprises a trace of a PCB(printed circuit board). 
     
     
         10 ] The electronic device according to  claim 1 , wherein the filter is not grounded directly. 
     
     
         11 ] The electronic device according to  claim 1 , wherein the at least part of the noise signal transmitted through the second signal leaks into an outside through an input/output connector. 
     
     
         12 ] The electronic device according to  claim 1 , wherein the first signal line or the second signal line corresponds to one of a differential signal, a single ended signal, and a high speed signal. 
     
     
         13 ] A method of dispersing a noise signal, the method comprising:
 transferring the noise signal through a first signal line;   transferring at least part of the noise signal through a filter; and   transferring the at least part of the noise signal through a second signal,   wherein both ends of the filter are connected to the first signal line and the second signal line.   
     
     
         14 ] The method according to  claim 13 , wherein the noise signal flows into the first signal line from an outside through an input/output connector. 
     
     
         15 ] The method according to  claim 13 , wherein the transferring of the at least part of the noise signal through the filter comprises:
 detecting the noise signal; and   short-circuiting the filter based on the detection result.
